Been a while, no pics on this one. Here is what I remember. For certian mine were welded in no bolts. Welded to /between the frame outriggers on either side of the door. Mine apparently had been left down and caught something, badly bent. I can't remember exactly why but with the floor out and the belly pan down it was easyer to repaired them in place. It took an tourch to heat/straighten and arc welder to reweld a seam. I do remember the most difficult part. A funky piece of angle steel, slit at the angle except for the ends with a lip that holds the steps up. aprox 1/16 x 1 1/2 wide. Welded into the step assembly, just below the door threshhold. Depends on "spring tension" for lack of the proper term, to hold the step up. NO adjustment. Had to heat/cool mine to shrink it somewhere around a 16th of an inch to get the proper tension to secure the step, real pain to deal with. While you're in there a number of us have found a flaw in the '64 safari. One or both of the body bows anchor bolts miss the frame outriggers either side of the door frame where they bolt down through the floor, attached only to the plywood. As the floor parimiter decays in the door area this allows movement and sometimes cracks in the skins around the door area. They only miss the out rigger by about an inch. Welding in an extension tab to the outrigger gives a solid attachment point for the body bow. Mine was so bad it even cracked the door frame. No doubt the bad axle and unbalanced running gear magnified the problem. If you rework the floor in the tail end there's a boltdown problem there also, much easyer than the door area.
